Chapter 10 Install and System Administration for FortiOS 5.0 : Basic Administration : Firmware : Configuration Revision
  
Configuration Revision
The Configuration Revisions menu enables you to manage multiple versions of configuration files on models that have a 512 flash memory and higher. Revision control requires either a configured central management server or the local hard drive. The central management server can either be a FortiManager unit or FortiCloud.
If central management is not configured on your FortiGate unit, a message appears to tell you to do one of the following:
enable central management (see Central management)
obtain a valid license.
When revision control is enabled on your FortiGate unit, and configurations backups have been made, a list of saved revisions of those backed-up configurations appears.
Configuration revisions are viewed in the System Information widget on the Dashboard.
